What does CGRN stand for in nursing?

CGRN stands for Certified Gastroenterology Registered Nurse. It is a specialty credential awarded by the American Board of Certification for Gastroenterology Nurses (ABCGN) to registered nurses who demonstrate advanced knowledge in gastroenterology and endoscopy nursing practice. The credential is recognized across the United States.

What is the format of the CGRN exam?

The CGRN exam is a computer-based test administered at PSI testing centers throughout the United States. It consists of multiple-choice questions with four answer options each. Candidates are given three hours to complete the examination, which is offered during specific testing windows each year.

What is the passing score for the CGRN certification exam?

The CGRN exam uses a scaled scoring system, and candidates need a scaled score of 450 or higher out of 600 to pass. ABCGN uses a criterion-referenced passing standard determined through a modified Angoff method. Results are typically available immediately after completing the computer-based test.

What topics are covered on the CGRN exam?

The CGRN exam covers patient care, procedures, and professional practice in gastroenterology nursing. Major content areas include upper and lower endoscopy, ERCP, pre- and post-procedure care, sedation and monitoring, infection control, equipment reprocessing, anatomy and physiology of the GI tract, and pharmacology related to GI conditions.

Who is eligible to take the CGRN exam?

Candidates must hold a current, unrestricted RN license in the United States or its territories. ABCGN requires at least 4,000 hours of gastroenterology nursing experience within the five years preceding application. This experience must be in direct patient care, education, administration, or research within the GI specialty.

How do I register for the CGRN exam?

Registration is completed through the ABCGN website at abcgn.org. Candidates submit an online application along with the examination fee, which is $325 for SGNA members and $425 for non-members. Once approved, candidates receive an Authorization to Test letter and schedule their exam through PSI.

How often is the CGRN exam offered?

The CGRN exam is offered during two testing windows each year, typically one in the spring and one in the fall. Each window lasts approximately two to three weeks. Candidates must apply before the application deadline for their chosen window, which usually closes several weeks before testing begins.

What are the best preparation tips for the CGRN exam?

Effective preparation includes reviewing the ABCGN Core Curriculum for Gastroenterology Nursing, studying the official content outline, and completing practice questions under timed conditions. Candidates should focus on endoscopy procedures, sedation protocols, and infection prevention. Joining a SGNA study group and reviewing current SGNA clinical guidelines also strengthens readiness.
